Glyphosate dynamics in a soil under conventional and no-till systems during a soybean growing season
(2018-08-01)Glyphosate (GLY) is a non-selective herbicide, heavily used world-wide in agriculture, especially under no-tillage (NT) management. The objectives of this work were i - to determine the temporal and vertical variation of ... -
Green bridge crops to manage corn nitrogen nutrition in the Southeastern Argentinean Pampas
(Elsevier, 2022-01-17)An ecological intensification of agriculture through the use of green bridge crops (GBC) between cash crops is a way to improve resource use efficiency. This study aimed to assess vetch (Vicia villosa Roth.) (Ve), oat ... -
Impact of crop aerial and root biomass inputs on soil nitrifiers and cellulolytic microorganisms
(Elsevier, 2019)In agricultural no-till systems, crop residue management has an important impact on the activity and abundance of soil microorganisms, which play a crucial role in soil health and quality. In these systems, when cover crops ... -
Infiltración en un Argiustol Udico con diferentes sistemas de uso en el Departamento 9 de Julio – Chaco
(Facultad de Ciencias Agrarias, Universidad Nacional del Nordeste, 2005)La infiltración de agua en el suelo juega un papel muy importante en la relación lluvia-escurrimiento y la disponibilidad de agua para las plantas. El objetivo de este trabajo fue caracterizar la infiltración de un Argiustol ... -
Intercropping of winter crops with perennial summer grasses in central Spain
(Universidad Politécnica de Madrid, 2020-04)The intercropping of summer-growing perennial grasses with winter crops or "Pasture cropping" is a no-tillage technique that might adapt to the climatic conditions of the central region of Spain. This system would allow ... -
Labranza cero bajo fertirriego por goteo para el cultivo de ajo colorado: estudio exploratorio en el valle bonaerense del Río Colorado
(EEA Hilario Ascasubi, INTA, 2017-04)El experimento consistió en analizar comparativamente el rendimiento de ajo colorado bajo un manejo con labranza cero (L0), respecto del sistema convencional con labranza (L1). En ambos casos bajo riego por goteo. -
Labranza cero en la producción de hortalizas pesadas bajo riego
(EEA Hilario Ascasubi, INTA, 2016-08)El informe desarrolla las líneas de acción del INTA H. Ascasubi y las experiencias en labranza cero en ajo, cebolla y zapallo que se presentaron en el XXIV Congreso de la Asociación Argentina de Productores en Siembra ... -
Labranza cero y fertirriego por goteo en la producción de zapallo anquito: análisis de la eficiencia en el uso de los principales recursos
(EEA Hilario Ascasubi, INTA, 2016-05)La tecnología para el cultivo de cucurbitáceas en la Argentina está constituida por una alta proporción labores de labranza. La diversidad de objetivos a cumplir implica una alta frecuencia e intensidad de laboreo, y la ... -
Long-term impact of no tillage in two intensified crop rotations on different soil organic matter fractions in Argentine Rolling Pampa
(2013)It is expected that the agricultural intensification occurred in recent decades in the Argentine Rolling Pampa significantly alters the SOM reserves. Therefore, it is necessary to identify soil organic carbon (C) and ... -
Mixed cropping regimes promote the soil fungal community under zero tillage
(2017-12)Fungi of yield soils represent a significant portion of the microbial biomass and reflect sensitivity to changes in the ecosystem. Our hypothesis was that crops included in cropping regimes under the zero tillage system ... -
Mollisol : biological characterization under Zero Tillage with different crops sequences
(2017-01)Zero tillage practices have a direct effect on soil microbial communities modifying soil productivity and sustainability. The crop sequences used can change the aforementioned properties, too. In this study, we evaluated ... -
Occurrence and distribution of soil Fusarium species under wheat crop in zero tillage
(2013)The presence of Fusarium species in cultivated soils is commonly associated with plant debris and plant roots. Fusarium species are also soil saprophytes. The aim of this study was to examine the occurrence and distribution ... -
Platy structure development under no-tillage in the northern humid Pampas of Argentina and its impact on runoff
(2017)The no-tillage system (NT) is widespread in the silty soils of the Argentine Humid Pampas. The aims of this study were i) to characterize the evolution of the structure of the A horizon in the northern Humid Pampas due to ... -
Soil quality and productivity under zero tillage and grazing on Mollisols in Argentina – A long-term study
(2017-12)The growing global demand for food, fibers and energy has triggered a scientific and political debate on how to attain increasing land productivity without further degrading soils. The objective of this study was to quantify ... -
Soil quality impacts of current South American agricultural practices
(Society for Urban Ecology, 2015)Increasing global demand for oil seeds and cereals during the past 50 years has caused an expansion in the cultivated areas and resulted in major soil management and crop production changes throughout Bolivia, Paraguay, ... -
Soybean and wheat response to lime in no-till Argentinean mollisols
(Elsevier, 2015-09)Crop production in Argentina has significantly increased over the past few years; this increase was consequence of better management practices which included P and N fertilization and, occasionally, S fertilization. Commonly ... -
Temporal Variation of Soil Physical Quality under Conventional and No-Till Systems
(2018-04)Determination of soil physical quality (SPQ) is very important because it is related to many important soil processes. However, it is not clear which indicators should be considered in this evaluation, and information about ... -
Temporal variation of soil sorptivity under conventional and no-till systems determined by a simple laboratory method
(2017-05)Soil water sorptivity (S) is an important property that measures the soil capacity to take water rapidly under capillary forces. Usually S is not included in soil laboratory routine experiments because there is not a widely ... -
